Good truckers, Bad truckers
Good cops, Bad cops
Good riders, Bad riders
Always a spoiled apple (or 2) in the bunch who make things more difficult for the rest. In ~16 years of driving I've definitely run across more of the good truckers, but I only remember the 10 or so bung holes who either intentionally or unintentionally tried to run me into the ravine or off the side of a mountain.
You're right bro, without them I've lives STOP! God light shine on a respected profession.
